CLX5640 is a copper leaching extractant used in the hydro-metallurgical process of copper extraction, including leaching and solvent extraction. It is a domestically produced product used in many copper cathode production units and factories in Iran. This product has gained widespread acceptance due to its high quality and performance, often surpassing foreign counterparts and Mextral5640 in various parameters.
Here are some key features and benefits of CLX5640:
1. High Copper Absorption: CLX5640 exhibits a high level of copper absorption, often superior to external samples of PLS (Pregnant Leach Solution).
2. Loading and Saturation: It allows for high loading and saturation levels in the pregnant leach solution.
3. Efficient Stripping and Copper Transfer: CLX5640 facilitates excellent stripping and copper transfer, ensuring efficient copper recovery.
4. High Selectivity: It offers excellent selectivity, particularly in terms of Cu/Fe selectivity.
5. Minimal Manganese Absorption: This extractant does not chemically absorb manganese, which can be a common problem in copper leaching processes.
6. Rapid Separation: CLX5640 exhibits favorable kinetics for absorption, phase transfer, and separation, resulting in minimal separation time.
7. No Formation of Undesirable Impurities: It does not lead to the formation of undesirable impurities like crud.
This product is crucial for copper cathode production using leaching and bio-leaching methods. It addresses the challenge of removing interfering ions such as iron and manganese, as well as silica, which is a common concern in many copper production facilities.
One of the notable advantages of using domestically produced CLX5640 is its competitive pricing compared to similar foreign products. It ensures a continuous and timely supply, ease of access, and free consultation regarding various product grades and models. The product is highly versatile and can be customized to meet specific customer requirements within the PLS system.
The chemical composition of CLX5640 includes a mixture of aldoxime and a specific hydrocarbon ester or high-flash-point solvent, enhancing its stripping power and optimizing its physical properties such as viscosity and density for effective use in the copper extraction process.
CLX5640 finds various applications, including initial charging of SX systems, daily or monthly makeup, bio-leaching processes (initial charge and daily injection), copper recovery from industrial wastewater containing significant copper ion concentrations, and copper extraction from sludge produced during aqueous processes.
The reaction of this extractant with copper ions is represented as follows:
2ROH(org) + Cu2+SO4(aq) ↔ (RO)2Cu(org) + 2H2SO4(aq)
CLX5640 plays a critical role in optimizing the copper extraction process, ensuring high-quality copper cathode production.
Magnesium carbonate is a white solid chemical compound with the chemical formula MgCO3, and it is a mineral salt. Magnesium carbonate is the result of the combination of magnesium and carbonate. Magnesium is a silvery metal with the chemical symbol Mg, and it is found in the alkaline earth metals column of the periodic table, referred to as the twelfth element. Additionally, magnesium is one of the eleven most abundant elements in the Earth's crust and the third most abundant dissolved element in seawater. Its significance for the human body lies in being the eleventh most abundant element within it.
The second component of this compound is the anion carbonate, with the formula CO3. As evident from its structure, it consists of a central carbon atom surrounded by three oxygen molecules.
Magnesium carbonate has various uses, including pharmaceuticals, dietary supplements for livestock and poultry, cosmetics and personal care products, the use of its alloys in the automotive industry and machinery manufacturing, and the use of its powder form to prevent slipping and enhance grip in sports such as gymnastics, weightlifting, bodybuilding, and more.
In pharmaceutical applications, magnesium carbonate, also known as magnesite, is used as an over-the-counter medicine for indigestion and relief from heartburn caused by excess stomach acid production. Magnesium carbonate functions by entering the stomach and reacting with hydrochloric acid to produce carbon dioxide and magnesium chloride, thus neutralizing excess stomach acid. However, it should be noted that its use should not be excessive, as it can lead to over-alkalization of the stomach and diarrhea.
In sports, magnesium carbonate aids athletes by absorbing moisture and sweat from the palms, helping them maintain a secure grip on weights or apparatus during exercises, preventing slippage, and enhancing their performance.
Magnesium carbonate is available in both mineral and synthetic forms, with synthetic magnesium carbonate typically having higher purity compared to the mineral counterpart. The magnesium carbonate produced by Nabo Exir Paya Shimi is of the synthetic type and, based on tests and analyses conducted on it, boasts a purity level exceeding 99%.
Nicolosamide is an organic chemical compound that acts as an anthelmintic (anti-worm) medication. Its chemical formula is represented as C13H8Cl2N2O4S, and it exists as a yellow powder with a crystalline structure, melting at approximately 225 degrees Celsius.
Nicolosamide is typically poorly soluble in water, which can have an impact on pharmacokinetic processes and absorption within the body.
It is an anthelmintic drug, meaning it is used to treat parasitic worm infections in both humans and animals. It is particularly effective against gastrointestinal tract worm infections. Here are some key details about Niclosamide:
Mechanism of Action: Niclosamide works by interfering with the energy production and metabolism of parasitic worms, ultimately leading to paralysis and expulsion from the body.
Use in Humans: Niclosamide is primarily used to treat infections caused by intestinal worms, especially for treating tapeworm infections like Taenia solium (pork tapeworm) and Taenia saginata (beef tapeworm). It is not commonly used for treating other types of parasitic infections.
Use in Animals: Niclosamide is also utilized in veterinary medicine to treat intestinal worm infections in livestock and domestic animals.
Drug Presentation: Niclosamide is typically administered orally in the form of tablets or semi-soluble preparations. The precise dosing regimen and treatment duration depend on the specific worm infection being treated, as well as the age and weight of the patient.
Side Effects: Common side effects of Niclosamide may include gastrointestinal symptoms such as nausea, vomiting, diarrhea, and stomach cramps. These side effects are generally mild and temporary.
Contraindications: Niclosamide should not be used in individuals who are sensitive or allergic to the drug. Additionally, it is not recommended for use during pregnancy and breastfeeding until the potential benefits outweigh the risks.
Precautions: It is important to use Niclosamide under the guidance and supervision of a healthcare professional experienced in the field of healthcare. Proper diagnosis and appropriate treatment guidance are essential, as Niclosamide may not be effective against all types of parasitic worms. Furthermore, post-treatment stool tests may be necessary to confirm the elimination of parasites.
Like any other medication, it is crucial to use Niclosamide under the guidance and supervision of a healthcare professional who can provide proper diagnosis and treatment guidance tailored to the specific parasitic infection. Self-medication is not recommended.
